Proximity Switches
Proximity switches are used to inform the computer of
the up and down positions of the knife and clamp. They
do not determine the stopping positions of the knife and
clamp, and therefore rarely need to be adjusted.
However, if a proximity switch is not sensing the knife
or clamp position correctly, it may need adjustment.
To check if the four proximity switches are sensing
correctly, go to Maintenance Mode and select
Diagnostic. Then select Sensor Data, and a list of
abbreviations for several inputs and outputs will be listed,
along with their status (0 for open, 1 for closed). The
four proximity switches should have the following status
during the various knife and clamp positions:
Knife Up

If any of the four proximity switches has a status of 0
when it should be 1, adjust the switch as described
below.
Knife Down Proximity Switch (Knfdwn)
Make sure the clamp and knife are in the up position.
Turn the power switch off and disconnect the power
cord. Open the front guard and the top hood.
Adjust the knife down proximity switch (fig. 33) by
loosening the two mounting screws and sliding the
switch closer to the knife bar. The gap between the
proximity switch and the knife bar should be 1/32” to 1/
16” (0.5 to 1.5 mm). No vertical adjustment is
necessary.
Clamp Up Proximity Switch (Clampup)
Make sure the clamp and knife are in the up position.
Turn the power switch off and disconnect the power
cord. Open the front guard, the top hood, and the upper
rear cover.
Adjust the clamp up proximity switch (fig. 34) by
loosening the two actuator mounting screws and sliding
the actuator up or down. The gap between the actuator
and the proximity switch should be 1/32” to 1/16” (0.5
to 1.5 mm).
Knife Up Proximity Switch (Knfup)
Make sure the clamp and knife are in the up position.
Turn the power switch off and disconnect the power
cord. Open the front guard and the top hood.
